Abstract
The invention provides a flat panel waveguide display, including: a fan out region, configured to allow light to experiences total internal reflection therein; a screen region, which comprises a front surface, a back surface and several side surfaces, the front surface is opposite to the back surface, wherein one side surface of the screen region optically connects to one side surface of the fan out region; and a first dielectric layer, coated on entire surface of the front surface of the screen region, wherein both of the fan out region and the screen region are made of waveguide material; wherein the first dielectric layer is divided into a first group of sections along direction of light path of light entering from the fan out region into the screen region, refractive index of each section of the first group is different from one another. Accordingly, the invention further provides a flat panel waveguide display system.
